Kappa Series 5.25" two-way speakers
Infinity Kappa Series speakers are built for drivers who want high-output sound in virtually any vehicle. The pair uses Plus One fiberglass woofers for deep, robust bass and 3/4" edge-driven textile dome tweeters that reach 40kHz. Power handling is rated at 60Wrms and 180W peak with 93dB sensitivity at 2.83V.
Drop-in fit with included hardware
Each box contains two speakers, foam gaskets, eight screws, eight speed clips and badges for a straightforward installation. The 133mm mounting diameter matches standard 5.25" openings so most factory locations accept them directly. Wiring to the 3.0 ohm terminals is simple, but verify polarity before powering the system.
Check amplifier match and mounting depth
Confirm your head unit or amplifier is stable at 3.0 ohms and can supply clean power near the 60Wrms rating. Measure the available depth behind the factory grille to ensure the speaker frame and magnet clear interior panels. Buyers needing a dedicated midrange driver or a three-way component set should look elsewhere.
